HGV Night Work: Working-Time Limits and Workforce Agreements Explained

How UK HGV night work limits work under Road Transport Working Time: the 10-hour night rule, night-time definitions, workforce agreements, and why they are not an individual opt-out.
This is general guidance for UK transport managers and operators. It does not replace official DVSA or Traffic Commissioner guidance, your operator licence conditions, or legal advice.

Legal requirement means the 2005 Regulations as summarised on GOV.UK. Official guidance is the annex wording. Operator procedure is how you roster and record. FleetPro practice is product labelling. This is general guidance, not legal advice.
Which working-time regime applies
GOV.UK’s working time rules annex splits the picture. Mobile workers regulated by assimilated or AETR drivers’ hours fall under the Road Transport (Working Time) Regulations 2005. Drivers under GB domestic drivers’ hours (or occasional mobile workers meeting the annex tests) sit under different 1998 Regulations provisions — including a possible individual opt-out from the 48-hour average that does not apply under the 2005 Road Transport rules.
The 10-hour night-work limit (2005 Regulations)
Legal requirement (Road Transport Working Time, as stated on GOV.UK): if night work is performed, working time must not exceed 10 hours in any 24-hour period. Night time is the period between 00:00 and 04:00 for goods vehicles (01:00–05:00 for passenger vehicles). The 10-hour limit may be exceeded if this is permitted under a collective or workforce agreement.
| Topic | GOV.UK position (goods / RT WTD) |
|---|---|
| Night time (goods vehicles) | 00:00–04:00 |
| Night-work working-time limit | 10 hours in any 24-hour period if night work is performed |
| Can the 10 hours be exceeded? | Only if a collective or workforce agreement permits it |
| 48-hour average opt-out | No individual opt-out under the 2005 Regulations |
| Reference period | Normally 17 weeks; 26 weeks if a collective or workforce agreement permits |
Working time for this regime includes driving and other listed work; periods of availability and breaks are treated differently from other work. Wrong tachograph modes invent the wrong night and average findings — train the mode switch as carefully as the roster.
Workforce agreements — not individual opt-outs
Official guidance: a collective or workforce agreement can permit exceeding the 10-hour night-work limit, and can extend the reference period for the 48-hour average from 17 to 26 weeks. Mobile workers must see details of any relevant agreement in advance.
What a workforce agreement is not
- It is not an individual signature that opts a driver out of the Road Transport 48-hour average — GOV.UK states there is no such individual opt-out under the 2005 Regulations
- It does not rewrite assimilated drivers’ hours driving, break or rest limits
- It is not a casual app acknowledgement or induction tick-box by itself
- It is not the same thing as a 1998 Working Time Regulations opt-out that may apply in GB domestic / occasional-mobile contexts
Rostering night work in practice
Operator procedure: define which duties count as night work for your operation, know whether a relevant agreement applies, and review night findings separately from daily driving limits.
Night-work control checklist
- Confirm whether RT WTD (2005) or 1998 provisions apply to the work
- Hold any workforce / collective agreement with the working-time records
- Show the agreement to mobile workers in advance
- Roster so 10-hour night working time is met unless the agreement lawfully permits more
- Capture other-employer hours when the worker has more than one employer
- Keep working-time records for two years after the period (2005 Regulations)
Health checks for night workers under the 1998 Regulations still matter where that duty applies — DVSA enforces those health-check requirements alongside working-time limits, per the annex. Annual leave questions sit with Acas, not with a tachograph report.
Drivers’ hours still apply at night
A legal night under working time can still break daily rest or weekly rest under HGV drivers’ hours rules. Conversely, a legal driving day can still breach the 10-hour night working-time limit or the 48-hour average. Analyse both clocks — see digital tachograph analysis.
- Do not silence a night-work problem by pointing at a later daily rest
- Do not silence a rest problem by pointing at a workforce night agreement
- Include night rules in induction — HGV driver induction checklist

Questions operators ask
Is the night window 00:00–04:00 or something else?
Can a driver sign to opt out of night limits?
No individual opt-out story replaces the need for a collective or workforce agreement where the law allows the 10-hour night limit to be exceeded. And that agreement still is not an opt-out from the Road Transport 48-hour average.
Does a workforce agreement change drivers’ hours?
No. It can affect certain working-time arrangements (night limit, reference period) where permitted. Assimilated driving, break and rest limits stay on their own clock.
What about GB domestic operations?
Different working-time provisions apply. Individuals may be able to opt out of the 1998 average 48-hour week, but employers cannot opt out of adequate rest. Read the annex section for domestic / occasional mobile workers and do not copy Road Transport night wording onto the wrong regime.
